Abstract

A dynamic position reporting and/or logging scheme is described herein. Position reporting and/or logging for a mobile device may be dynamically determined based on one or more reporting and/or logging constraints. The constraints may be based on time, distance, events, operating parameters, operating conditions, or some combination thereof. The constraints that dynamically trigger position reporting may be the same as, overlap, or be distinct from the constraints used to trigger position logging. The reporting and logging constraints can be selected to provide a more accurate indication of a track or route traveled by the mobile device.

Claims

1. A method of dynamic position reporting, the method comprising:

initializing position reporting to a central registry over a wireless communication link;

determining a position of a mobile device;

determining a status of at least one reporting parameter;

initiating a position report to the central registry based on the status of the at least one reporting parameter;

changing a status of a dynamic reporting parameter upon detecting that the mobile device performed a turn; and

initiating a further position report to the central registry based on the changing of a status of the dynamic reporting parameter after detecting that the mobile device has performed the turn.

2. The method of claim 1, further comprising:

determining a status of a first reporting parameter; and

resetting a reference value associated with a distinct second reporting parameter based on the status of the first reporting parameter.

3. The method of claim 1, further comprising storing the position in memory based on at least one logging parameter.

4. The method of claim 1, wherein changing the status of at least one reporting parameter comprises changing the status of at least one of a time, distance, or course reporting parameter.

5. The method of claim 1, wherein changing the status of at least one reporting parameter comprises comparing a value associated with a first reporting parameter to a reference value for the first reporting parameter.

6. The method of claim 1, wherein initiating the position report comprises:

determining a report type; and

transmitting the position report of the report type to the central registry.

7. The method of claim 6, wherein determining the report type comprises determining the report type based on the status of the at least one reporting parameter.

8. The method of claim 6, wherein determining the report type comprises determining the report type based on a ranking of criticality of information.

9. The method of claim 6, wherein determining the report type comprises determining the report type based on wireless channel conditions.

10. The method of claim 1, wherein changing the status of one dynamic reporting parameter comprises determining a status of a velocity reporting parameter.

11. The method of claim 10, wherein resetting the value of the at least one reporting parameter comprises at least one of modifying a time reporting threshold or modifying a distance reporting threshold for initializing position reporting to a central registry.

30. The method of claim 1, wherein a turn represents a change in a direction of movement of the mobile device from a previous direction of the mobile device.

31. The method of claim 1, wherein the status of the dynamic reporting parameter is changed when a change in an angle of the turn exceeds a predetermined angular threshold.

32. The method of claim 1, further comprising resetting the status of at least one reporting parameter upon detecting that the mobile device performed the turn.

12. A method of dynamic position reporting, the method comprising:

initializing position reporting to a central registry over a wireless communication link;

initializing a reference value associated with each of a time reporting parameter, a distance reporting parameter, and a course reporting parameter;

determining a position of a mobile device;

changing a status of at least the course reporting parameter upon detecting that the mobile device has performed a turn;

initiating a further position report to the central registry based on the status of the course reporting parameter and upon detecting that the mobile device has performed the turn; and

resetting the reference value associated with each of the time reporting parameter and the distance reporting parameter based on the status of the course reporting parameter.

13. A dynamic position reporting apparatus, the apparatus comprising:

a position location module configured to determine a position of a mobile device;

a position data manager coupled to the position location module and configured to initiate a position report based on a status of at least one reporting parameter, changing a status of a dynamic reporting parameter upon detecting that the mobile device has performed a turn; and

initiating a position report to the central registry based on the changing of a status of the dynamic reporting parameter upon detecting that the mobile device has performed the turn; and

a communication transceiver coupled to the position data manager and

configured to transmit the position report over a wireless channel to a central registry.

14. The apparatus of claim 13, further comprising a Satellite Positioning System (SPS) receiver coupled to the position location module, and wherein the position location module determines the position of the mobile device based in part on signals received by the SPS receiver.

15. The apparatus of claim 13, further comprising at least one positioning sensor, and wherein the position location module determines the position of the mobile device based in part on output received from the at least one positioning sensor.

16. The apparatus of claim 13, wherein the position data manager comprises:

a memory;

a data logger configured to log the position received from the position location module to the memory based on at least one logging parameter.

17. The apparatus of claim 16, wherein the position data manager further comprises a reporting manager configured to determine the status of the at least one reporting parameter and generate the position report based at least in part on one or more the position stored in the memory.

18. The apparatus of claim 13, wherein the position data manager comprises a reporting manager configured to determine the status of the at least one reporting parameter and generating the position report including at least the position of the mobile device.

19. The apparatus of claim 13, wherein the position data manager is configured to determine a position report type based on the status of the at least one reporting parameter.

20. The apparatus of claim 13, wherein the dynamic reporting parameter comprises a velocity reporting parameter.
